DESCRIPTION
Interface Enable RX Gain Control
Low active, input enable of the serial RX gain control interface
Interface Enable TX Level Control
Low active, input enable of the serial TX level control interface
Power Switch of Receive Path
High active, digital CMOS input levels
Power Switch Transmit Path
High active, digital CMOS input levels
RF Receive Input 1
Low noise amplifier input. The 50: matching is, in part, the bond/package inductance and an external
component (tbd).
RF Receive Input 2
Complementary signal to RFRX1
Ground Supply of Radio Frequency Receive Circuit Modules
Voltage Supply of Radio Frequency Receive Circuit Modules
RF Transmit Output 1
P1dB up to +10dBm @ 50: differential 3.5GHz. The 50: matching is, in part, the bond/package
inductance and an external component (tbd).
RF Transmit Output 2
Complementary signal to RFTX1
Voltage Supply of Power Amplifier Driving Module
Voltage Supply of Radio Frequency Transmit Circuit Modules
Digital Test Bus Input/Output Digital
DTB input/output signal for testing purposes, connection and direction is configurable over SPI.
Power On Reset
Low active, open drain output with internal 10k: pull up resistor
SPI Data Digital Output
SPI Enable Digital Input
The rising edge of SCL and a low SDE indicate the start of a data transmission to the SPI slave
SPI Data Digital Input
Serial SPI data input stream is initiated with SDE and begins with an address byte. Input is MSB first. The
MSB of the address byte is the R/W control bit. A number of data bytes follows after the address byte. The
actual number of data bytes depends on the address.
SPI Clock Digital Input
At every rising edge, the SDI data is latched into the internal SPI register. SDO data change also on the
rising edge.
Voltage Supply of SPI Interface Pads
Voltage Supply of Digital Circuit Modules
Ground Supply SPI Interface Pads and of Digital Circuit Modules
